As long as the syntax is correct, the validator shouldn't care what names  
or values your meta properties have.

To determine the exact probem, please provide a link to the documents in  

Without seeing those documents (or even the error message - you forgot to  
paste that into your message), my only guess would be that you might have  
forgotten to enclose the property names in quotes.

You should be using something like this:

<meta name="MyProperty" content="MyValue">

By the way, most of the meta properties mentioned in your e-mail are just  
a waste of bandwidth; modern search engines ignore them completely (i.e.,  
they won't even index the page based on the content of those tags). You  
can find a list of the meta tags used by search engines at each search  
engine's website. For example, here are the meta tag properties that  
Google uses:
